Plastic Water Lines

by Sherm Turner

Dear Mr. Plumber,
We are building a new house from the ground in Michigan. Our builder wants to install plastic water lines in the house. Is this any good? What is the code? Could the plastic water pipes leak?

Dear Mikey,
Yes, you could and will have leaks using plastic water lines in Michigan. The plumbing code for nearly all the frigid states requires copper pipe and fittings. You never stated what type of plastic pipe but certain types have been outlawed / banned from use in colder climates.
